So it looks like Section 2.3, "Reserved EAPIs" is more relevant here:

    2.3 Reserved EAPIs

        EAPIs whose value consists purely of an integer are reserved
        for future versions of this specification.

        EAPIs whose value starts with the string paludis- are reserved
        for experimental use by the Paludis package manager.

That means that, yes, EAPIs can be literal string values (just without
quotes).  However, the primary use case, IOW, the official repo, we're using
incrementing numeric integers.  PMS is supposed to be package-manager
agnostic, so carving out a specific reservation for a specific package
manager in Section 2.3 seems to defeat that purpose.

If Paludis is still being developed and needs something for experimental
use, then it's up to it to do that on its own.  We could support this by
specifying that EAPIs are single-line strings of a form [A-Za-z0-9\x20_-]+?,
thus removing the specific reservation for a specific package manager and
handling the current single-number format as well as other fancy names.
Like maybe EAPI 9 can be "Magnificent Penguin"? :)
